The Sekonic L-308X-U Flashmate Light Meter was designed to meet the needs of next generation image makers as the mosts versatile and affordable light meter. The Flashmate retains the compact and intuitive design of its predecessors while blending the best features and functionality of the L-308S and L-308DC. New features include the long-awaited LCD backlight, Aperture (F) priority and ISO 850 for cinema camera's native ISO.

A Legacy of Accuracy
Pocket-sized and exceptionally accurate, the Flashmate L-308X-U Light Meter from Sekonic is a compact tool for metering both ambient and flash lighting as well as working in video with dedicated Cine and HD Cine modes. Equipped with a sliding lumisphere, the L-308X-U is able to measure ambient light as well as reflected light via a lens with a 40 degree reception angle. This meter also has a wide metering range; from 0 to 19.9 EV at ISO 100, and can work with flash within a range of f/1.0 to f/90.9 at ISO 100. Repeat accuracy is also important when metering, which the L-308X-U delivers with a rating of <0.1 EV on repeat exposures.

Maximum Versatility 
Last year, Sekonic introduced their groundbreaking flag ship light meter, the Speedmaster L-858D-U. By merging functionality for both photography and cinematography into one light meter, Sekonic created a powerful and invaluable tool for image makers of every kind. Now Sekonic is brining that philosophy to the immensely popular L-308 series with the new Flashmate L-308X-U.

Three Ways to Meter:
Sekonic created the L-380X-U to be the three meters in one to keep pace with the demands of modern image creators. It features three metering modes:

Photo Modes: For still image pgorographers, featuring shutter or aperture priority display of a full range of ambient and flash functions including cord and cordless flash measurement, as well as ambient EV measurement. 

HD Cine Mode: Perfect for DSLR and mirrorless videographers who need to take exposure readings and control light using shutter speeds and frame rates. Plus, get aperture settings with one-tength stop accuracy.

Cine Mode: Designed for use with cinema grade cameras, allows users to select from the most useful frame rates and shutter angles for exposure control with one-tenth stop accuracy.

Users in every mode can easily switch between incident and reflected light via the sliding Lumisphere. HD Cine and Cine mode users can measure illuminance in either Lux or Foot Candles with the optional Lumidisc.
